Marking of road works = Dispositions pour la circulation pendant les travaux routiers = Verkehrsmassnahmen bei Strassenbaustellen = Verkeersmaatregelen bij wegopbrekingen.

When road works are in progress, the normal flow of traffic should suffer the least possible disruption. In order to limit the danger to traffic, special attention should be paid to a correct marking of the site, and to advance warnings to drivers that are approaching road works.
